Question

我正在尝试使用gradle applicationVariants mergeAssets任务从我的apk中删除一些未使用的资源文件。

即使我能够打印“此行打印”这一行，但当应用程序变体“运行”时，似乎似乎没有调用variant.mergeAssets.doFirst {}，我从未在gradle控制台中看到输出“此行未打印”。我试图删除的资产也没有删除，但似乎删除它的代码永远不会执行。

我做错了吗？我已尝试将整个android.applicationVariants任务移到buildTypes之外，我已尝试将其嵌套在release{}中。我尝试过的任何内容似乎都无法正常工作。

buildTypes {
    release {
        runProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), file('proguard-project.txt')
        signingConfig signingConfigs.release
    }

    publicBeta.initWith(buildTypes.release)
    publicBeta {
        runProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), file('proguard-project.txt')
    }

    android.applicationVariants.all { variant ->
        println 'this line is printed'
        variant.mergeAssets.doFirst {
            println 'this line is never printed'
            File fonts = file("${rootDir}/build/intermediates/exploded-aar/com.github.johnkil.android-robototextview/robototextview/2.0.1/assets/fonts")
            if (fonts.exists()) {
                for (File file : fonts.listFiles()) {
                    if (file.getName().contains("RobotoSlab")) {
                        println("delete " + file.getName() + " font")
                        file.delete()
                    };
                }
            }
        }
    }
}

以下是gradle控制台输出，为简洁起见：

将始终打印打印的行，因为它在配置阶段执行。（见Gradle User Guide）

您的gradle控制台输出显示所有合并*资源任务被跳过为UP-TO-DATE。这意味着自上次执行任务以来输入和输出没有改变，因此gradle不再执行它们。不幸的是，Gradle还不够聪明，知道你已经改变了任务实现，并且它不应该跳过任务。

尝试运行清理以强制运行任务

Gradle应用程序变量mergeAssets不起作用
